Jennifer Lopez Arriving at Hollywood Week Auditions Pictures

Jennifer Lopez was back to work for her second day in a row at American Idol's Hollywood Week auditions held in Pasadena, CA yesterday. She arrived in another sexy and sophisticated outfit following the bright yellow ensemble she wore for Tuesday's taping. Jen was chauffeured to set by a black SUV, but it's a convertible J Lo gifted to Casper Smart that's getting all the attention since she recently surprised him with a white Bentley. The couple's relationship seems to be cruising smoothly into 2012, but their unexpected hookup and her surprising breakup with ex Marc Anthony both landed on our list of biggest headlines of the year.
